Health bonus

A health bonus (or health potion) is an item that is introduced in E1M1: Hangar of the first Doom episode Knee-Deep in the Dead, alongside its armor equivalent, the armor bonus. Appearing in the very first room of the game, the two items are likely to be the first to be picked up by the player. It has the appearance of a small, round blue bottle with a glowing liquid inside. Doom 64 has a very similar, albeit slightly more angular design with a longer neck. Picking one up increases the player's health by 1% up to a maximum of 200%, except in Doom 64 and in console ports such as the Atari Jaguar and Sony PlayStation versions, where it instead increases health by 2% per bottle.

Health bonuses are included in the items percentage displayed at the end of each level.
